I.
Tighten clevis locknut (46).
J.
Relieve air pressure to actuator.
K.
If used, replace adjustable indicator (88) to
lever (34) with screws (89).
Note: If required, adjust indicator (88) to front
cover (32) indicator marks with the valve in the
closed position.
L.
Replace front cover (32) and rear cover (29)
and secure in place with cover screws (30).
M.
Replace spring barrel boss cover (58) and
bottom cover (11). (Snap fit.).
Note: Prior to placing the valve in service,
operate the valve actuator through one complete
cycle to insure proper functioning.
N.
If desired, set handwheel (53) or optional
limit stop (77) to desired position.
Changing service requirements or service conditions
may require a change in flow direction through the
Camflex® II valve. Figure 19 illustrates the various
positions and flow directions in which the valve may
be placed to accommodate requirements.
To change body position proceed as follows:
A.
Refer to figure 19 and determine which is the
desired valve position, flow direction and which
actuator position is required.
B.
Proceed to the appropriate section of this
instruction for the required disassembly and
assembly procedures.
A.
Remove front cover (32) and rear cover (29) by
removing the two cover screws (30).
B.
Remove spring barrel boss cover (58) (Snap fit.).
C.
Remove bottom cover (11) (Snap fit.).
D.
Using a manual loading panel, apply sufficient air
pressure to the actuator to move the lever (34) to
an intermediate position.
E.
Remove clevis pin clips (5) and remove clevis
pin (7).
F.
Position lever so it does not contact handwheel
powerscrew assembly.
G.
Remove Truarc ring (50) and washer (51) from
handwheel powerscrew assembly.
H.
Unscrew and remove handwheel powerscrew
assembly from yoke (33).
I.
Remove handwheel thread plug (48).
Note: If the actuator is equipped with the
optional limit stop (77), in place of the handwheel
thread plug, it must be removed.
J.
Insure spring barrel is properly supported.
K.
Loosen and remove capscrews (36) and
lockwashers (37) then remove spring barrel (38).
L.
With the yoke assembled to the valve in the
required orientation, place spring barrel (38) on
desired yoke Location and secure with
capscrews (36) and lockwashers (37), and
tighten firmly.
M.
Screw in handwheel powerscrew assembly into
the power screw hole of the yoke which is on the
opposite side of the spring diaphragm actuator.
Note: Handwheel action is always the same as
air action and opposes the spring.
N.
Replace handwheel washer (51) and truarc ring
(50) and back off handwheel so the power screw
will not interfere with the operation of the lever.
O.
Replace handwheel thread plug (48).
Note: If the valve is equipped with the optional
limit stop (77) instead of the thread plug, it must
Caution: Changing the body position and flow
direction could also require relocating the
actuator. Insure that the actuator location and
action are in accordance with the
recommended positions and modes
illustrated in figure 19. Illustrations are shown
looking at the body through the bonnet with
the actuator in front of the valve. The plug
shaft is always rotated in a clockwise
direction by the actuator to open the valve.
12. Changing Body Position
13. Changing Actuator Action
Caution: Do not exceed pressure listed in
figure 14 for actuator used. Do not use
handwheel to move lever.
Caution: Depending on the size and weight
off the actuator, it is recommended that
proper lift and support procedures be utilised
when removing the spring barrel or yoke.
Caution: If the orientation of the actuator to
valve requires that the yoke be rotated about
the valve, it is recommended that section 12.
on changing yoke position be accomplished
before proceeding.
